I heard of this. My immediate criticism, is that even those with diagnosed ADHD aren't just deficient in focus/attention and impulsive in all aspects of their lives. They can drive a car, play video games, read subjects they are interested in, have long conversations, etc. That is to say, focus/attention/arousal are rather complex phenomenons that vary greatly based on circumstances, and aren't simple numbers we can say one is deficient in. Testing someone in a completely artificial environment (sitting in an office during a diagnosis playing some tasks clicking on a computer screen) is hard for me to believe is exactly an accurate metric for revealing any of these things. Most especially, when a lot of people are actively seeking this diagnosis, and are motivated to alter their behavior to get the result they are looking for. Im really curious how this company decided these tests are accurate at all. I assume they did some studies to find some variability in the test results and those who were already diagnosed and then determined those variability were indicative of ADHD. So what test is really doing IMO is just reinforcing the standard diagnostic criteria. |

You are right that attention is a complex phenomenon, but keep in mind that people who evaluate ADHD are aware of the limitations -- that is why TOVA isn't typically the only mechanism used for diagnosis. ADHD evaluation often involves multiple sessions in which other possible explanations are ruled out or explored, along with questionnaires from friends and family who know the person -- incidentally some of the questions on the ones I collected from my friends/family were about my driving!
Even with this, there are still limitations, but there's no need to throw the baby out with the bathwater -- the goal is to produce an actionable explanation that we can use to reduce suffering, and for many people this explanation does exactly that.
